CNC Gear Hobbing Machine Model

YS3140CNC&YS3140CNC/4

MIAN FEATURES

The model YS3140CNC is a high-speed gear hobbing machine with six axes controlled。By b siemens 840D system.The six working axes are respectively radial feed of Column ,axial feed of hob head ,cutter spindle rotation ,worktable rotantion ,hob head swivel and tangential hob shifting. (radial feed of column,axial feed of hob head,cutter spindle rotation and worktable rotation).Exchange gears adopted on old gear hobbing machines are now replace by electronic gear boxes,and therefore the machines is featured in nice transmission rigidity ,high working accuracy and very easy setting-up and operation

The cutter spindle and worktable spindle are supported by rolling bearings and actuated by cylindrical gear pairs.Sliding guideays of column are of steel material and coated with Teflon and tharefore features in ample bearing force and nice vibration rssistance.To guarantee the machine’s cutting accuracy,heat-exchange measures have been taken to create a the mathine is high in working rigidity and Stable in cutting accuracy and can perform high-efficiency and high-precision cuting operations for gears with a module up to 12.
